Can it be “tommyrot” when such people advocate Pelmanism? (Oct, 1925)

2009-11-20T17:36:20Z

Can it be “tommyrot” when such people advocate Pelmanism?

Here are only a few of many famous men and women who advocate Pelmanism, and who use its principles themselves. With this testimony before you, can you doubt that it will benefit you ? Find out what Pelmanism has already done for over 650,000 people—send for a copy of the free book illustrated below.

NO doubt you have often heard of Pelmanism, but probably you have carelessly thought of it as “just another new-fangled movement. Some more tommyrot! The usual mental-pep stuff!”

Can it, however, be “tommyrot,” when such people as those pictured here, men and women of the highest intelligence and distinction—prominent statesmen, artists, novelists, jurists, business men, military men, publicists—advocate Pelmanism in the most enthusiastic terms?

Pelmanism has spread, with the force of a religious movement, all over the world. There is no secret as to how it performs its seeming miracles of regeneration among discouraged people. It takes the principles of Applied Psychology, simplifies them so that they can be understood by everybody, and then arranges them into a remarkable system of mental training.

The results of this system are sometimes almost unbelievable. It helps its users in the most practical way. It changes their outlook upon life; it changes their circumstances. They begin to accomplish things they had heretofore only dreamed of. They do more, earn more. Instances are on record (on file and open to inspection), where income has increased 800, 900, and 1,000 per cent. Yet, remarkable though they may seem, these results can be simply explained.

. Be honest with yourself. You know in your heart that you have failed, failed miserably, to attain what you once dreamed of. Was that fine ambition unattainable? Or was there just something wrong with you? Analyze yourself, and you will see that at bottom there was a weakness somewhere in you.

What was the matter with you? Find out by means of Pelmanism; then develop the particular mental faculty that you lack. You CAN develop it easily; Pelmanism will show you just how; 650,000 Pelmanists, many of whom were held back by your very problem, will tell you that this is true.

The whole remarkable story of Pelmanism is told in a little book, “Scientific Mind-Training.” It explains in detail the simple principles; it tells stories—almost unbelievable, some of them— of people whose lives and circumstances have been revolutionized after a short time.

We will gladly send this book to you, free, if you are at all interested in Pelmanism. To ask for it involves you in no obligation whatsoever; you will not be bothered; no salesman will call on you. Send for this book now; when such distinguished people as those shown here advise you to take up Pelmanism; how can you justify yourself if you do not try to find out, at least, whether Pelmanism can help you “find yourself.” Mail the coupon below—now, before you forget about it.

Perfect Numbers

Six is such a number: it is the sum of all numbers that divide it except itself. In 2,000 years 12 perfect numbers were found; now a computer has discovered five more

by Constance Reid

THE GREEKS, greatly intrigued by the fact that the number 6 is the sum of all its divisors except itself (1+2 + 3), called it a “perfect” number. They wondered how many other such numbers there were. It was easy enough to ascertain by trial that the second perfect number was 28 (1+2 + 4 + 7+14). The great Euclid was able to prove that in all cases where a number can be factored into the form 2^n-l(2^n—1) and 2^n—1 is a prime number, the number must be the sum of all its divisors except itself. Thus in the case of 6, n is 2 and 2^n—1=3, a prime number; in the case of 28, n is 3 and 2^n—1 = 7, again a prime number. With Euclid’s formula it was no difficult matter to compute that the third and fourth perfect numbers were 496 (n=5) and 8,128 (n = 7). But beyond that the computation became laborious, and in any event it was not proved that this rule included all the perfect numbers. Euclid left for future mathematicians a challenging question: How many perfect numbers are there?

In more than 2,000 years mathematicians were able to turn up only 12 numbers that met the strict requirements for numerical perfection. Within the past year, however, the University of California mathematician R. M. Robinson has, with the aid of a modern computer, discovered five more. The discovery did not attract the attention of the press. Perfect numbers are not useful in the construction of atomic bombs. In fact, they are not useful at all. They are merely interesting, and their story is an interesting one.

For many centuries philosophers were more concerned with the ethical or religious significance of perfect numbers than with their mathematics. The Romans attached the number 6 to Venus, because it is the product of the two sexes—the odd (masculine) number 3 and the even (feminine) number 2. The ancient Hebrews explained that God chose to create the world in six days rather than in one because 6 is the more perfect number. The eighth-century English theologian Alcuin pointed out that the second origin of the human race, from the eight human beings on Noah’s Ark, was less perfect than the first, 8 being an imperfect number. In the 12th century Rabbi Josef Ankin recommended the study of perfect numbers in a program for the “healing of souls.”

THE mathematicians, meanwhile, had been making slow progress. The first four perfect numbers—6, 28, 496 and 8,128—had been known as early as the first century. Not until 14 centuries later was the fifth discovered. It was 33,550,336 (n=13). Then in 1644 the French mathematician Marin Mersenne, a colleague of Descartes, announced six more at one clip, and thereby linked his name forever with perfect numbers. The numbers were now so large that they were necessarily described only by the prime number 2^n—1, or, more briefly, by the exponent, n, in Euclid’s formula. The values of n for the 11 perfect numbers, including Mersenne’s six new ones, were 2, 3, 5, 7, 13, 17. 19, 31, 67, 127 and 257. In other words, the largest prime in the series was the enormous number 2^257— 1.

It was obvious to other mathematicians that Mersenne could not have tested for primality all the numbers he had announced. But neither could they. At that time the only method of testing was to try every possible divisor of each number. By this laborious method mathematicians did test Mersenne’s first eight numbers and found them prime.

It was the great Swiss mathematician Leonhard Euler who tested the eighth number (2^31 —1). Euler also proved that all even perfect numbers must be of the form expressed by Euclid’s theorem. No odd perfect number has ever been found, but it has never been proved that such a number cannot exist.

For more than 100 years the perfect number formed from the prime 2^31 — 1 remained the largest proved. Then in 1876 the French mathematician Eduard Lucas worked out a method by which a possible prime could be tested without trying all potential divisors. At the same time he announced that he had tested 2^127—1 by his method and found it prime.

According to Lucas, the number 2^n—1 is prime if, and only if, it divides the (n— 1) term of a certain series. In this series the first number is 4 and each succeeding number is the square of the preceding one minus 2; in other words 4, 14, 194, 37,634, and so on. For example, to test the prime number 7 (2^3—1), one divides 7 into 14; the n—1 term in this case being the second number in the series, since n is 3. Since 7 divides evenly into 14, it is prime by Lucas’ test.

Obviously even Lucas’ short-cut method becomes rather unwieldy when, as in the case of 2^127—1, one must divide 170,141,183,460,469,231,731,687,303,-715,884,105,727 into the 126th term of Lucas’ series. For such numbers, mathematicians use a short-cut of the shortcut: instead of squaring each term of the series, they square only the remainder after they have divided the number being tested into it.

Even with the help of Lucas’ method mathematicians were not able to finish testing all of the possible Mersenne numbers until a few years ago. Their tally showed that Mersenne’s list of perfect numbers was incorrect. He was right on nine numbers (those for which n is 2, 3, 5, 7, 13, 17, 19, 31 and 127), but he was wrong on two he had listed (those with the exponents 67 and 257), and he had missed three numbers in the series (with exponents 61, 89 and 107). Thus the list stood at 12, with 2^126(2^127 —1) the largest known perfect number.

THEN on January 30 last year Robinson fed the problem to the National Bureau of Standards’ Western Automatic Computer, known briefly as SWAC. This is a high-speed machine: it can do an addition of 36 binary digits in 64 millionths of a second. Robinson’s job was to break down the Lucas method into a program of the 13 kinds of commands to which the SWAC responds. The job was complicated by the fact that, while the machine is built to handle numbers up to only 36 binary digits, the numbers he was working with ran to 2,300 such digits. It was, he found, very much like explaining to a human being how to multiply 100-digit numbers on a desk calculator built to handle 10. To tell SWAC how to test a possible prime by the Lucas method, 184 separate commands were necessary. The same program of commands, however, could be used for testing any number of the Mersenne type from 2^3—1 to 2^2297—1.

The program of commands, coded and punched on paper tape, was placed in the machine’s “memory.” All that was then necessary to test the primality of any Mersenne number was to insert the exponent of the new number as it was to be tested. The machine could do the rest, even to typing out the result of the test—continuous zeros if the number was a prime.

The first number to be tested was 2^257—1, the largest of the 11 numbers announced by Mersenne. Twenty years before it had been found not prime by D. H. Lehmer, who worked two hours a day for a year with a desk calculator to do the test. It happened that this evening Lehmer himself, now the director of research at the Bureau of Standards’ Institute for Numerical Analysis on the U.C.L.A. campus, was in the room. He saw the machine do in 48 seconds what had taken him an arduous 700 and some hours. But the machine got exactly the same result.

SWAC then continued on a list of larger possible primes. Mersenne had said that all eternity would not suffice to test whether a given number of 15 or 20 digits was prime. But within a few hours SWAC tested 42 numbers, the smallest of which had more than 80 digits. One by one it determined that they were not prime. Finally at 10 p.m. a string of zeros came up: the machine had found a new perfect number. Its prime was 2^521—1. Just before midnight, 13 more numbers later, another prime came up: 2^607—1. In the decimal system this is a number of 183 digits.

The machine continued testing numbers when opportunity afforded during the next few months. Last June the number 2^1270— 1 was found to be prime. In October, concluding the program, it established as prime the numbers 2^2203 —1 and 2^2281l—1. The latter is the largest prime number, of any form, now known.

The perfect numbers of which these primes are components are, of course, much larger—so large that in comparison with them conventionally “astronomical” numbers seem microscopic. Yet, by a proof as old as Euclid, mathematicians know that these numbers are the sum of all their divisors except themselves—just as surely as they know that 6=1 + 2 + 3.

They still do not know, however, how many perfect numbers there are.

Aluminum Man Startles London (Jan, 1929)

Aluminum Man Startles London

He talks, walks, stands, sits down, rolls his eyes and waves his hands, but he isn’t a man at all — nothing but a mechanism of steel and aluminum, cables and gears and electric motors! His life-like actions astonished London at a recent scientific exhibition.

ALL LONDON recently flocked to see “Eric,” the talking mechanical man who opened the popular scientific exhibition organized by the British Model Engineer. With an anatomy composed mainly of steel rods and bars, and a stylish suiting of sheet aluminum, he is an ideal representative of the race of Robots who at some future date are to dominate the world. At least, we have been told so in a very successful play, and many people are seriously looking forward to the time when much of the toilsome labor will be performed by mechanical workers.

“Eric” weighs a little over 100 pounds; he will get up and bow at the word of command, he will make a speech, he will answer questions, he will move his arms, and head to give point to his remarks, and when told to sit down, he obeys at once without a protest. He is very docile, but his eyes flash while he is speaking, and crackling sparks at his mouth give brilliance to his oratory.

He is actuated by 12-volt electric motors, supplied with current from a battery. There are wheels, belts, levers, and joints, all ingeniously geared up to give the required movements. His speech is the voice of his master, or of his master’s man, but how it gets to “Eric’s” lips is one of the mysteries which W. H. Richards and A. H. Reffell, the joint inventors, are not yet prepared to disclose. His powers in this direction have been turned to good account, for he has earned the distinction of being the first mechanical man to open an exhibition. At the appointed hour on the opening day, he solemnly rose and bowed to a gathering of some thousands of eager folk drawn thither by the remarkable rumours which had run like wildfire round London during the previous week. Unabashed by the tumultuous applause which greeted him on rising, he delivered a most eloquent oration, descriptive of the purpose of the Exhibition, and then formally declared it open to the public.

Many prophecies have been made as to “Eric’s” future. He is not yet prepared to scrub floors, or do the domestic washing and ironing, nor can he operate a hand-crane or a lathe. But he would make an excellent salesman in a department store, telling the virtues of the bargains there displayed. At present he is merely a clever combination of well-known mechanical and electrical devices arranged and dressed to grip the popular imagination.

Sixty billion vibrations per second (May, 1956)

Sixty billion vibrations per second

A great new giant of communications—a waveguide system for carrying hundreds of thousands of voices at once, as well as television programs —is being investigated at Bell Telephone Laboratories.

Such a revolutionary system calls for frequencies much higher than any now used in communications. These are provided by a reflex klystron tube that oscillates at 60,000 megacycles, and produces waves only 5 mm. long.

The resonant cavity that determines the frequency is smaller than a pin-head. The grid through which the energizing electron beam is projected is only seven times as wide as a human hair, and the grid “wires” are of tungsten ribbon 3/10,000 inch in width. G. K. Farney, University of Kentucky Ph. D. in nuclear physics, is one of the men who successfully executed the development of the klystron. Dr. Farney is a member of a team of Bell scientists whose exciting goal is to harness the immense bandwidth that is available with millimeter waves . . . and to make certain that your telephone system remains the best in the world.

70-YEAR OLD TOURIST CROSSES U. S. ON BICYCLE

AN ORDINARY bicycle with a special baggage support above the front wheel is the equipment used by M. C. Plummer of Portland, Maine, in touring the United States. Mr. Plummer is 70 years old but he covers from 50 to 150 miles every day on his bicycle, depending on the weather and the nature of the country to be traveled. The sack of bedding, food and clothing which he carries on his handlebars weighs 80 pounds but is so well balanced that the 70-year old tourist has no difficulty in controlling his two-wheeled automobile. Mr. Plummer recommends this system of traveling as a health builder. He does not try to cover any specified distance each day, but sleeps wherever he happens to find himself at sunset.

GUN TRADERS’ SUPERMARKET

You can get anything from a blunderbuss to a burp gun at this busy swap session.

ANY exhibition of guns, old or new, has a fascination for men of all sorts, from serious shooters and collectors to Walter Mittys who have never fondled anything more lethal than a cap pistol. The Gun Traders’ Market, a periodic event at Klein’s Sporting Goods Store in Elmwood Park, Ill., near Chicago, brings together a wide assortment of shooting irons and a large crowd of gun lovers from miles around. For those who only look, the trading and the traders are just as interesting as the guns. The event brings new customers, good will and lots of would-be Davy Crocketts to Klein’s.

New Machine Makes 600 Shoes in Eight Hours

SIX HUNDRED pairs of shoes in eight hour is the record set by the new shoe manufacturing machine recently exhibited at the Leather Fair in London, shown in the photo below. It resembles a gigantic wheel, the spokes of which contain the electrical devices which control the operation of the mechanism on the wheel’s rim. There is room for 14 pairs of shoes on the rim of the wheel. This type of invention is in keeping with the general trend of manufacturing efforts to increase the production of finished products with less overhead expense in both man power and mechanical power.

I Shampoo the Sidewalks of New York

A bright idea and home town pride prompted this ex-sweater manufacturer to beautify the city’s neglected pavements. Now he reaps the reward.

By Louis Schwartz

EAST Side, West Side, all around the Town . . . my Sidewalk Sanitation Service has made its debut and though it doesn’t cover quite as big an area as the song does—yet—I hope S.S.S. will be just as familiar before long.

I started this business a year ago by convincing one department store manager in New York City that scientific, mechanized methods could restore beauty to his sidewalks, at less expense than old-fashioned wash-’em-down methods. Today many of New York’s leading stores and hotels, stretching over some 40 city blocks, have signed up for my beauty treatment.

Where did I get the idea for a business as unusual as this? Well, having seen men scrubbing sidewalks by hand a hundred times without giving if much thought, one day I wondered: Why should people use such primitive methods outdoors while. they operate by pushbuttons indoors? Right then I started dreaming of a practical method to give stores and hotels better and cheaper cleaning service. Street cleaning is the city’s responsibility but sidewalk shampooing is left up to the property owners. Why couldn’t I relieve them of this responsibility—and make a few dollars doing it? I also wanted to have a hand in beautifying New York, my home town.

Then the fun began. Aside from watching my wife clean house, I had no background at all for my proposed occupation. Before the war I was in the ladies’ sweater manufacturing business. Then I became a navigator on a B-24 and served in the South Pacific where the girls don’t wear sweaters. No sidewalk sanitation in the picture yet. But I have always liked to tinker and I went to work on my new idea wholeheartedly, experimenting and doing research, checking with city authorities and consulting manufacturers.

I concocted several cleaning compounds and tried some of them out on the Fifth Avenue sidewalk in front of Bergdorf Goodman, one of New York’s ritziest stores. There are many different types of cement pavement. I wanted to discover the compound best adapted to all types. Every night for a couple of weeks I stationed myself in front of Bergdorf Goodman, poured on the detergent, then scrubbed away with a brush. After scouring for a while and noting the effect on the pavement, I’d go home.

. There were always some taxicabs parked across the street from the store and the drivers would watch my antics with vast curiosity. I used to see them wink at each other when I made my nightly visits but I tried not to let it upset me. Much later, when I was ready to give a real demonstration of my cleaning service to some city officials, one of the hackies came over to me and confessed: “Gee, brother, am I glad to know at last what you’re doing! Confidentially, we used to think you were a little . . . ah . . . you know. As I say, I’m sure glad that things are cleared up now.”

But that was much later. First I spent considerable time helping to design our special scrubbing machines. Then I had to get permission from the city to use the machines on the pavements while working out the most efficient cleaning techniques. All told, it cost about $15,000 to get started.

As we finally worked it out, through trial and error, there are three separate steps to our cleaning technique. The first operation consists of general debris removal. You’d be surprised, as I was at first, to see how much dirt accumulates on those famous sidewalks of New York. The worst offender is chewing gum. But we evolved a high-pressure steam machine which, together with my compound, goes to work on the pores of the cement and does a first-rate cleaning job. This machine also restores the original color of the sidewalk.

After this initial conditioning, our big baby goes to work. I’m very proud of our two three-wheeled monsters which resemble tanks as they lumber up and down the sidewalks. Actually, they’re patterned after the city’s own street cleaning machines, adapted to our own special use. Each holds a 150-gallon water tank which, since the water shortage began in New York, I fill with chlorinated river water mixed with my chemical detergent.

Nozzles strung across the 5-1/2-ft.-wide bottom of our tanks spray the treated water on the sidewalk. This mixture attacks the dirt in the cement and a big brush attached in front of the rear wheel sweeps and scrubs. The operation is very effective. It also pleases the city officials, as well as our customers, since all litter is actually picked up—sucked into a hopper—and not just tossed aside for someone else to pick up. Some of the stores take this service five nights a week and the hotels usually subscribe to it seven days a week.

On the busy sidewalks of the world’s largest city, our little “tank” arouses great curiosity.

When we first tried it out about a year ago, it was quite a traffic stopper.

One woman onlooker recently told one of my men that she was tremendously impressed with what he was doing and that she would personally go and speak to the mayor and ask him to duplicate our service on all the streets of New York. Who knows, maybe she did! Anyway, I do know that good will always pays off.

I also worked out a little patrol machine which constitutes the third phase in our service. We have ten of these machines now. They resemble carpet sweepers and my men use them during the day to pick up cigarette stubs, fine dust and any other debris that doesn’t belong on a sidewalk. Stores take this service at least three times during the day, hotels more often.

In winter, S.S.S. is also in the snow removal business. We are the only private snow removal company in the city, equipped to give service on a large scale. We’re on call day and night, Sundays and holidays, with gasoline-driven snowplows. The Weather Bureau notifies us when a storm is brewing and we have on file the names of some 500 college students who are willing to pitch in as soon as the flakes begin to whirl.

Our quest for cleaner sidewalks doesn’t confine itself to New York. We are in the $100,000 business bracket and are negotiating with men in other cities who will join Sidewalk Sanitation Service on a franchise basis. These men, whom I screen very carefully, buy all the necessary equipment through me. For approximately $20,000 they get the machines and complete instructions. I make the contacts for these men, getting in touch with civic groups as well as merchants, because we must have the complete cooperation of everyone concerned. A franchise operator’s income depends on how much ingenuity he puts into the work. He should earn somewhere between $5,000 and $10,000 the first year.

Often our men are asked if they ever find anything valuable as they scour the sidewalks. Beyond an occasional “clink” which indicates that the machine has picked up some metal (which usually turns out to be a nail or perhaps a penny) we haven’t had any exciting finds. But I am thrilled that our work has found such quick acceptance, which is the really valuable find I’m looking for. The future looks bright. I can visualize sparkling, shampooed sidewalks stretching across the U.S.A. In the words of a little white-haired lady who was watching our tank in action, “It’s about time.”

RUMPLER Designs Largest Plane

Herr Rumpler, famous designer of Germany’s war time fighting planes, is turning his peace time activities to good account in developing the world’s largest airplanes. Rumpler, shown above in a characteristic pose at his drafting board, is now building an enormous monoplane which will have wings large enough to place staterooms in. A new blunt-nosed wing section is used to effect this design. Huge wheels, 10 feet in diameter, will be used on the landing gear. All motors will be easily accessible in flight. Navigating quarters will be in a cabin atop the wing.

The new Rumpler monoplane, now nearing completion in Germany, will have a span of 300 feet and a chord of 50 feet. It will be so large that space between the sides of each wing spar will be used for hallways, staterooms and motor compartments. A specially designed, power operated air field railway track will be constructed for housing the new giant. The cross section drawing shows the disposition of the arrangement. The plane will cruise at 82 m.p.h. A gigantic hangar is shown in the photo below with the big ship on the track. Note room for two of these monsters.

NEW MOTORCYCLE CAN ATTAIN SPEED OF 100 M. P. H!

RECENTLY the Ascot Paulhan Co.. of London, announced a new model motorcycle that is attracting wide attention.

WHY MARRIED MEN VISIT PROSTITUTES (Jan, 1959)

WHY MARRIED MEN VISIT PROSTITUTES

What are the motives which lead a married man, often with an attractive and “willing” wife, to patronize a common woman of the street?

by Albert Ellis. Ph.D.

“I SUPPOSE,” said my marriage counseling client, “that you think I’m crazy for spending so much of my time and money on the women I pick up in bars— when my wife, as you have seen, is such a fine and attractive woman.”

“It does seem a bit peculiar,” I replied, “considering that your wife, if I am to believe her story, is very much in love with you and is quite aggressive in her desire for frequent marital relations.” – “Yes, I guess it does seem peculiar. And, let me tell you, she’s being honest with you. She does want sex relations very often, and she is, as you can see, a fine figure of a woman. When I think how 1 felt about her before marriage! You’d never believe it.”

“But now—?”

“Now, frankly, she leaves me cold. Not that I don’t still admire her as a person. And, as the mother of our two children, I think she’s perfectly great. Couldn’t want anything better. But sexually! Sure she’s responsive — in theory. But just as soon as I give in to her need, all she does is lie supinely and leave the entire role of love-making completely to me.”

“If I understand you correctly,” I said, “your wife wants you to do the active lovemaking, while she, once coitus begins, does little or nothing. Is that right?”

“That’s exactly right — or exactly wrong, if I may coin a phrase. While the other women I go with—for the right payment and half a kind word—they’ll do almost anything I want. And they seem to get satisfaction out of it, too, a good many of them. Now do you see why I prefer them to my good-looking, fine, respectable young wife?”

I did see, very clearly. And I often see why many of my married clients patronize prostitutes, from high-class “call girls” to two-dollar women of the street, even when they have handsome and “willing” wives. For their wives, in many instances, are only willing within definite limits. They may be willing to have face to face coitus— but to try no variations of intercourse, which they consider “unnatural.” Or when these wives do try varied sex positions or acts which their husbands particularly desire, they do so reluctantly, listlessly, and guiltily, thus taking away all their husbands’ satisfaction.

Prostitutes, on the other hand, are in the business of satisfying their customers. For a stipulated fee, they will do almost anything a male desires; and will do so, in most instances, freely, guiltlessly, with verve.

Why, then, says many a male, even if he loves and respects his wife and wants to keep their marriage together, should he not patronize the woman who makes it her business to satisfy him sexually?

Other reasons why literally millions of married men regularly or irregularly patronize prostitutes include the following:

1. Many males, even though they derive satisfaction from sex relations with their wives, feel that they need a variety of partners. Some want a different type than their wives—such as a blonde instead of a brunette, or a young instead of a middle-aged woman.

Others simply want a different individual from the one with whom they participated a day ago or a week ago. The quickest and easiest way for many of these males to find a different partner is to patronize a prostitute.

2. In many instances, husbands who do not normally need sexual variety find they have no wish to remain abstinent when they are separated from their wives, when their wives are ill, or when they desire intercourse more frequently than the wives do. Again, resort to prostitutes may be easier in these instances than engaging in extramarital affairs.

3. Some men who crave variety feel that patronizing prostitutes is safer, less involving, and more loyal than having non-prostitutional affairs; and in many instances their wives agree with this viewpoint and tolerate their seeing a prostitute far better than they would tolerate a non-prostitutional relationship.

4. A surprisingly large number of men, I have found in my clinical experience, fail miserably in their marital relationships, largely because of their ignorance and prudery in regard to how to satisfy their wives sexually.

Such men are frequently impotent or sexually below par because, consciously or unconsciously, they subscribe to self-defeating sex notions which sabotage their powers and potentialities. Out of shame, they avoid having marital relations and resort to prostitutes with whom, because they pay, they are not ashamed to be poor lovers.

5. Occasionally, a man’s wife refuses to use proper birth control technique; and, rather than have intercourse with her and risk having unwanted children, he patronizes women of the streets.

6. Some men’s wives are so stingy of affection, and demand so much in return for having steady sex relations, that the male finds it actually cheaper and less emotionally blackmailing to visit prostitutes.

7. Once in a while, a man becomes deeply attached to a prostitute and keeps patronizing her, rather than bedding with his wife, because he genuinely cares for her and enjoys her company more than that of his spouse.

8. Some men, particularly those with low self-esteem, ignore the monetary element in their patronage of harlots, and convince themselves that they are making one real conquest after another in the course of such patronage. To them, even a paid “conquest” is satisfying.

9. Many husbands, for a number of neurotic reasons, occasional- ly or steadily visit prostitutes. Some thus vent their hostility against their wives. Others masochistically want to degrade themselves. Others find it impossible to be fully potent with a “good” woman. Still others seek the danger of an illicit encounter.

For a host of fearful, hostile, or guilt-laden reasons, or to erect defenses against their underlying irrational anxieties, such individuals find temporary “solutions” to their problems by bedding with a prostitute.

In general, then, a married man will resort to prostitutional affairs either for relatively sane reasons —such as the sexual inaccessibility of his wife—or for irrational ones —such as his unwillingness to face the real reasons for his being sexually unsatisfied in marriage.

In almost all cases where I have had personal contact with married males who steadily frequent women of the street, the irrational and neurotic reasons for so doing were predominant. This may partly result, however, from the fact that most people who seek my counsel are, as one might expect, fairly disturbed.

Where married males are regular patrons of prostitutes, and where they want to do something about their basic sex and general problems, cure or significant improvement is usually effected in reasonably short order.

In the case of the man whose wife refused to take an active part in coitus, it was a simple matter to induce her to participate more actively and more responsively.

At least, it was simple once I had shown him that his negative attitude toward her was encouraging her resistance in this connection, and that the more he worked at being nice to her and inducing her to be a more satisfactory sex partner, the better results he would be likely to attain.

In most instances, the husband’s neurotic attitudes about himself, about sex, about his wife, and about prostitutes must be explored.

One of my patients, for example, felt that he was so worthless that none but a prostitute, not even his own wife, could really care for him or find satisfaction in sex relations with him.

Another was patronizing call girls regularly because he was still rebelling against his mother’s early lectures against his having illicit affairs. Unconsciously, he still wanted to spite her as well as his wife (who, symbolically, he saw as another mother-figure) rather than primarily to go after the kind of sex-love satisfaction he really wanted for himself.

When irrational, early-acquired attitudes such as these are ruthlessly exposed in the course of counseling or psychotherapy, and relentlessly attacked in the light of the individual’s real goals and satisfactions, the prostitutional affairs of most men are voluntarily or spontaneously stopped.

No Shrink- No Spot (Apr, 1947)

2009-10-30T15:50:32Z

No Shrink- No Spot

A DISTANT cousin of the sulfa drugs, melamine, is being used to “cure” some of the serious “ailments” of textiles.

Its most striking use is in a resin which, applied to woolens, solves the age-old problem of shrinking and matting in water.

In another form, melamine resins can be used to impregnate acetate rayons and cottons to make them spot resistant. Ink, coffee or other staining liquids, spilled on clothes made from treated fabrics, can be washed off with a damp cloth or a glassful of water.

Melamine was first developed in 1834 but was forgotten until a few years ago. It went to war in a resin applied to blankets, sleeping bag linings, socks, and insect netting. But it is in its peacetime application to textiles that melamine promises its widest use.

SEVEN WAYS TO GET A RAISE! (Jun, 1967)

2009-10-30T15:53:48Z

SEVEN WAYS TO GET A RAISE!

By James Berry

YOU’D like a raise. But how can you get one? Pay boosts depend on your boss’ decision. But helping him make that decision—in your favor—is often up to you.

Getting a raise merely because you deserve it is not only very rare, it is Dullsville. Where’s the fun? Life is a game when you know you’re worth more than you’re getting and you’re taking steps to get what you’re worth. Look at it that way—and remember that in nearly every job you must take steps to get as much as you deserve.

Here are the ways to go about it. You may use one or more or all of these tactics, singly or in sequence, but if you ever get the raise the chances are you will use at least one of them.

1. Know what the boss wants. Some guys knock themselves out for years and all they do is bug the guy they’re working for because they don’t give him what he wants. Jim Cassett, a marketing analyst in an ad agency, put in hours of overtime each week. The boss never mentioned it. One day Jim heard the big boy speak kindly about the neatness of someone else’s report. Jim quit working overtime. He worked on making the reports neat and clear. Within three weeks the boss was patting him on the back; within four months he was working on a hotter account—with a $10-a-week raise.

It’s easier to know what the boss wants when you’re in close contact, harder when you work for a big firm, with straw bosses, possibly in trouble themselves, between you and the real Leader.

In any company you must decide which boss to try to impress. Your immediate supervisor is first choice. If he is fair and confident of his own job, he’ll support fair requests for raises and promotions. If he’s indecisive, he’ll base his judgment of you on what his bosses think of you. In such a case, look aboveyour immediate boss to see the guy you must impress.

2. Get yourself known. Companies often see participation in community and firm affairs as the sign of leadership and sound character. Go to company dinners, join teams, committees, and other organizations to gain recognition. Become active in charity drives, volunteer fire departments and fraternal organizations.

There are other ways. Ted Kobin, a sheet metal worker, got his name recognized by keeping up a regular flow of sound ideas to his firm’s suggestion box. One of his first ideas was to mark each steel sheet with the code number of the machine it was meant for. This saved the company hundreds of dollars a year by avoiding mixups. By his fifth or sixth idea, Kobin’s name was known to most of the plant’s executives. He got a $10 weekly increase months before it was due.

3. Improve your skill. Leo Pacy, a 33-year-old lathe operator, asked his boss to send him to a night course in his specialty. The boss agreed and for three nights a week for six months Pacy improved his skill at the firm’s expense. Four months after he finished the course, his company got an order that demanded special lathing techniques Pacy’s course had covered. He was one of the men assigned to the new project —with $20 weekly raise.

Sometimes a company will pay for a school training course. Unions and trade associations sometimes run seminars or workshops covering your job specialty. Attend. If no such help is at hand, consider paying for outside training yourself. If no courses or workshops are available, read all you can about your field. This can often push your performance high enough to merit a raise.

4. Ask for the raise. Ted Lawrence, a waiter, worked harder than ever after the restaurant was expanded. His paystayed the same. Ted braced the boss and got the raise immediately. If he had brooded a few more weeks before asking, he would have got the raise that much later. Sometimes the boss knows you should have a raise but needs a nudge; sometimes he thinks “Why raise him until he asks for it?” Don’t count on the boss to be a hero.

Times not to ask for a raise: when the firm has just lost a big customer, when firm earnings are taking a dive, when the boss’ wife has just gone out and run up a big bill or had divorce papers served on him. When under a strain the boss may fire his best employee instead of giving him a raise—just to relieve his feelings. The monster is only human.

When asking for a raise, offer the standard reasons, using discretion. (Using discretion means don’t lie about anything he can check up on easily or knows about already). The reasons are: you have taken on more work, are doing the work more efficiently, men doing the same job are getting paid more elsewhere, the cost of living is rising, your family is increasing, you have doctor’s bills or other unavoidable added expenses. Emphasize the positive reasons —those involving your value to him— over your difficulties in living on your present pay.

5. Shoot for a promotion. Art Capatano, a shipping clerk, asked his fore-man if he, Capatano, was a candidate for an assistant traffic manager’s job that would open soon. The foreman said yes but that a man with accounting experience was wanted. In one blow Capatano let his boss know he was interested in the job, found that it had not been filled, and what training would help him land the position. Capatano went to an adult education course in accounting— and let his boss know, just casually. Three monthslater the job opened and Capatano got it— with an $18 raise.

When keeping an eye open for promotions, don’t only think of your department. Talk to the men and the foremen in other departments; there may be higher turnover, less skilled competition or lower seniority.

If your job is unionized, you might have a different problem in stalking a promotion. Often, the salary that goes with a given job is pegged by a union contract. In this case, your chance for a wage boost might lie working through the union as well as through your immediate boss.

Often, becoming active in union affairs aids in being shifted to a different job category where the pay is higher for similar work. Sometimes you can apply for a supervisory position through the union itself, which often recommends its own candidates to the company. Then, participation in a union often leads to landing an official position within the organization such as shop steward.

6. Get a better job. Today, employers in almost every field are screaming for efficient, honest, and qualified workers. If you have qualities that merit a raise, and you don’t get it, chances are another employer will pay you what you deserve.

Keep on the lookout for job offers in trade journals, newspapers, and professional meetings. The manager of an upstate New York service station was repeatedly refused a raise despite added work loads. Then, he attended a regional sales meeting sponsored by the automobile company that gave his station its dealership. From an acquaintance, he heard that the manager of a service station in a nearby town was moving to Florida. His colleague helped arrange an interview with the owner. The manager got the new job and a salary boost of $20-a-week.

7. Say you’re quitting. Often an employer just doesn’t take time to estimate the worth of an employee. Consequently, requests for wage raises are parried with vague promises that never seem to materialize. But one way to make the boss face the value of your services is by presenting the possibility of his losing them. •

Woman Scientist’s Process Makes Glass Invisible (Apr, 1939)

2009-10-29T23:21:33Z

In the next issue: “Woman Scientist’s Invention Makes Water Wet!”

Woman Scientist’s Process Makes Glass Invisible

GLARE from reflected light, which has made it difficult to see pictures framed under glass at certain angles, has been removed by a new process developed in General Electric’s research laboratory by Dr. Katherine B. Blodgett (above).” By applying thin chemical films to the surface of glass, Dr. Blodgett has been able to nullify or neutralize rebounding light rays with the result that pictures framed with glass so treated appear as though there was no glass at all, regardless of the angle viewed from, as represented by center panel section of the portrait above.

The process consists of building or attach-ing to the glass a very thin transparent film of about four millionths of an inch, or exactly one-quarter wave length of light, in thickness. As light falls upon the film, rays are reflected from both the upper and lower surfaces. With the film exactly one-quarter wave length in thickness, the rays coming from the outer or upper surface are equal in intensity to those rays reflected from the lower surface, thus counteracting one another, and no light is reflected. The non-glare treatment of glass promises to have a wide-spread application in the field of camera, telescope and all other type lenses, including eye glasses although the process is still in the laboratory stage.

NEW PRODUCTS of scientific and mechanical interest

A THERMOSTATICALLY CONTROLLED SOLDERING iron is announced by the Sound Equipment Corporation of Glendale, Cal. The Kwikheat takes only 90 seconds to be ready for use by means of a 225 watt heating unit controlled by the thermostat. Eliminating the excessively high temperatures acquired by ordinary irons during the idle period, this new iron has an unusually long life expectancy.

Six different threaded tips are available, one of which is an alloy melting pot. The iron, U.L. approved, is designed for A.C.

THE ROTAKIT, something new for the home workshop enthusiast and mechanic, has been announced by the Nicholson File Co. of Providence, R. I. It is built in the shape of a miniature bench stand and enables the worker to keep all his rotary files and burs in plain sight. A glass front serves to protect the files from dust.

Three assortments are available: No. 20 containing ten Ground Burs; No. 30, ten hand cut Rotary Files; No. 40, five Ground Burs and five Rotary Files. These can be used for die-making, pattern making, mold finishing, tool making, or wherever else a precision file or bur is needed for finishing.

A “LIFT-OUT” RADIO is one of the features in the new Westinghouse line of phono-radio combinations being produced at their Sunbury, Pa. plant. The radio which forms the front part of the combination can be easily lifted out for use as an independent set. The unit, known as the Duo, accepts 12 10-in. or 10 12-in. records for automatic playing.

Three other table models and five consoles have also been announced. A new power circuit is another feature of these radios. Called Plenti-Power it practically doubles the output of pre-war sets using the same number of tubes.

KITCHEN VENTILATORS are wanted by 96 out of every 100 women according to a recent survey. The ILG Electric Ventilating Company of Chicago is now producing three sizes for small, medium, and large kitchens (see photo below) as well as portable models equipped with adjustable panels for sliding sash window frames. An automatic model is also available which eliminates manual pull-chain operation.

A TEN OUNCE POCKET RADIO, small enough to fit into your pocket, without crowding and measuring 3 in. wide, 6-1/4 in. high and only 3/4 in. thick is now in actual production by the Belmont Radio Corp. of Chicago. The extreme compactness of this newmidget is made possible by the use of tiny radio tubes, the same kind used in hearing aids and of the type used in the radar proximity fuse. These tubes weigh about a tenth of an ounce and have a cross section about the same as an oval cigaret. Prices for these midget sets will start at about $30; they will be available in gold, silver, two tone metal and various leathers.

A PNEUMATIC SAW designed to speed-up and simplify sawing and filing operations is now being distributed by the Air-Speed Tool Co. of Los Angeles, Calif. The saw. built to operate with about 85 pounds of pressure, has an adjustable barrel which readily permits cutting in metals or woods as well as intricate dead end, keyhole and scroll work.

Long trouble-free life is assured since the saw has only two internal operating parts. There are no gears, adaptors, or power-take-off devices.

This new tool weighs only 3-1/2 pounds.

A DE LUXE PHONOGRAPH COMBINATION housing a 14 tube chassis equipped for Frequency and Amplitude Modulation reception. Television, and Wire Recording is now being manufactured by the Lear Radio Co., of Grand Rapids, Mich. The console has a 14 inch speaker and a de luxe record changer. List prices range from $500 to $600. The modern classic lines of these consoles have been designed by a leading Grand Rapids designer.

A WASHER THAT HAS EVERYTHING INCLUDING THE KITCHEN SINK is now here due to the efforts of the Hurley Machine Co. of Chicago. The Thor Automagic washing machine does the daily dishes and the weekly washing at a selling price, according to the manufacturer, of less than many pre-war washing machines. It can be purchased as a dish washer or as a clothes washer alone and the accessories added at a later date. Eight pounds of clothes and dishes for six is the capacity of the washer. Proposed attachments will include an ice-cream freezer, a home churn, and a potato peeler.

Take A Seat—But Watch For Splinters

MANUFACTURERS of upholstered furniture, who are no longer able to get metal for springs because of priorities, were invited at a furniture show recently to take a look at the spring pictured at right. Band-sawed from a piece of wood, this spring has plenty of resilience, may well replace in many peacetime functions spring steel needed for war uses. Weight for weight, it is said to be as strong as steel.

Scientists Invent Machine To Discover How Brain Works (Apr, 1935)

Scientists Invent Machine To Discover How Brain Works

THE brain, perhaps the most mystifying organ of the human body, can now be scientifically studied by a new apparatus which photographs amplified “action currents.” Invented by Dr. H. H. Jasper and Dr. L. Carmichael of Brown University, the new machine will permit physicians to study the action of the brain just as the electrocardiograph permits a revealing study of heart action.

A headpiece on the head of the patient picks up electric currents of about one ten-millionths of a volt which flow from the brain in waves, at a rate of from eight to fifty per second. The currents are carried to an amplifying box where they are intensified 500,000 times and flashed across a glass disc. The ordinary currents are smooth and wavy; when the mind is disturbed, they are sharp and irregular.

Freckles Frozen Off With Dry Ice (Feb, 1933)

2009-10-28T16:53:09Z

I’m going to guess that freckle used to be synonymous with mole. Otherwise, this could take a while. Also, I love the assumption that readers are all white.

Freckles Frozen Off With Dry Ice
FREEZING off freckles by means of pencils of compressed carbon dioxide snow, often called “dry ice,” is a new method of getting rid of these skin blemishes devised by an Italian physician, Dr. M. Matarasso. The dry ice, which will freeze all human tissues solid after contact of more than a few moments, is compressed into a small stick or pencil, sharp-pointed like a lead pencil. The point of this pencil of concentrated cold then is pressed against each freckle in turn for three seconds. After the colored skin of the freckle drops off in about a week, the new skin thus disclosed is white and unmarked.

Novel Ice Cream Dispenser

SODA jerkers and confectioners who are called on to “dish up” ice cream cones will appreciate the labor-saving features of a new tray which holds the cones in such a manner that both hands are free for the filling operation. Aside from its time-saving aspect, the tray permits the salesman to pause in his work of filling the cones in case he is called on to serve a rush customer.

The section containing the holes which hold the cones fits over a wooden tray base, so that the device comes in two parts. Advertising copy for ice cream manufacturers can be imprinted on the holders.

Inside The Music-Box of Giant Bells (Mar, 1936)

2009-10-28T16:52:33Z

Inside The Music-Box of Giant Bells

IN the bell loft of the Rockefeller church in New York it suspended the first of the tuned carrillons, the smallest bells of which are shown above. The resonance of a bell, which lasts for several moments, has previously prevented accurate tuning of carrillons, but this age-old annoyance has been eliminated by a system of bell dampers invented by G. M. Giannini.

Right—Where the ancient carrillon players pulled an assortment of ropes, the modern musician sits down to his instrument like an organist. Electricity and compressed air swing the weighty clappers. Left—The Rockefeller church in New York, where thousands are delighting in the tuneful melody of the bells.

Above—The “Music Box” of the giant carrillon. Each peg represents a note in the melody, struck electrically when the giant drum revolves automatically. Left—This damper suppresses the tone of the bell the instant it is no longer contributing to the melody. The damper is the secret of carrillon tuning, and was discovered by Giannini, a young electrical engineer. Each note can thus be heard distinctly, not submerged in a dissonant chorus.

Violin Made Of New “Glass”
ANEW type of unbreakable, flexible material which has the same transparency as ordinary glass, but weighs less, size for size, has been invented in Germany. A product of artificial resins, the new material can be bent, twisted, punched, cut with a scissors, polished and sawed. As a demonstration of the possibilities of the new “glass,” the full-size violin shown above was made entirely from sample sheets, with the exception of the usual strings.
